Hi everyone. I found that the stress in the moving cylinder increases with its stiffness and the moving velocity .
It appears that the interia effect should be the reason for non-zero stress state in the cylinder. This means that the cylinder is not in equilibirum internally and zero-stress...
Hi corus.
I put in real properties and the conclusion is unchanged. The cylinder connected with fixed shell display zero stress, while cylinder conected with moving shell show non-zero stress.
how come the strss state relate to kinetic energy?
Is it because the stress wave was genenated at...
Hi ESOcomposites.
I totally agree with you and DanStro that the stess value in order of 1E-16 is negligible practically.
The problem I have is that I can not figure out why and how the non-zero stress come out from theoretical viewpoint.
My limited knowledge on ABAQUS prevents me from...
Hi DanStro.
Thank you for your reply.
In that model, the cylinder properties are arbitrarily defined and have no physical meaning, so the stress values are not 'true' but reveal that the stress deviates from the theoretical value - zero.
I have confirmed that stress connected with fixed...
Hi everyone.
I have a question about ABAQUS simulaiton results.
I am running a trial simulation to test ABAQUS codes and get results that puzzle me a lot.
The FE model consists of 4 parts- 2 cyliners with some distance and 2 shells sandwiching the 2 cylindrs (Pls see attachement for model...
